Tshem tawm fuse cutout thiab load switching fuse cutout yog siv sab nraum zoov siv high voltage tiv thaiv ntaus ntawv, Tobe txuas nrog incomin-g feeder ntawm tis transformer los yog tis kab, nws tsuas yog tiv thaiv transformeror kab los ntawm luv luv Circuit Court thiab overloading, thiab on / off loading, tam sim no, poob tawm fuse cutout yog tsim los ntawm insulator kev txhawb nqa thiab fuse raj ntsia ntawm ob sab ntawm kev sib cuag thiab kev txhawb nqa. fuse tube, Fuse tube yog tsim los ntawm sab hauv arcexting raj. Sab nrauv phenolic compound ntawv raj lossis epoxy glasstube, Load switching fuse cutout muab enfored elastic auxiliry contacts thiab arc-extinguishing exclosure rau switching on-off loading tam sim no.
Thaum ib txwm ua hauj lwm ntawm fuselink nruj lub fuse tube yog fixfed los ntawm nyob ze txoj hauj lwm, nyob rau hauv cov ntaub ntawv system tshwm sim faults, txhaum tam sim no tshwm sim nyob rau hauv lub fuse yaj tam sim ntawd thiab coj piece hluav taws xob yog, uas cia arc-extinguishing raj raug rhuab thiab fexplode ib tug lotofgas, Th-os yuav ua rau siab siab thiab hauv qab no ntawm cov yog nrog rau cov yeeb nkab txuas ntxiv, tom qab c fuse txuas ntxiv zog. thiab fuse tube tso tawm, Cutoutnow yog nyob rau hauv txoj hauj lwm qhib, Thaum nws xav tau kom tshem tawm thaum lub sij hawm txiav tawm loading, operat-los yog yuav tsum los ntawm insulating kev khiav hauj lwm bar rub lub txav kev sib cuag, atits pib lub ntsiab kev sib cuag thiab auxiliary static contactis contactedst-ill, Whiling rub lub auxiliary kev sib cuag yog sib cais ntawm pab neeg sib cuag muaj tshwm sim hluav taws xob arc thiab arc arc arc yuav bent ntev. lub caij no arc-exting explode gas kom tshuab tawm lub arc thaum tam sim no dhau xoom
